摘要/Abstract

摘要： 以梅鹿辄和赤霞珠葡萄为实验材料，研究延迟采收对葡萄类黄酮物质的影响。结果表明：延迟采收后酿酒葡萄果粒质量和果粒纵径均降低，可溶性固形物的含量增加，可滴定酸含量降低。梅鹿辄果皮中共检测出19 种花色苷、6 种黄烷醇和15 种黄酮醇，延迟1 周后，黄烷醇和黄酮醇含量增加，相较于对照分别增加了69%和1.67%，延迟2～3 周后黄烷醇和黄酮醇含量降低；而延迟采收后，花色苷含量下降。赤霞珠果皮中共检测出15 种花色苷、4 种黄烷醇和15 种黄酮醇，花色苷、黄烷醇和黄酮醇的含量在延迟3 周后显著增加，相较于对照分别增加了22%、102%、80%。

Abstract: The effect of delayed harvest on grape flavonoids of Merlot and Cabernet Sauvignon was qualitatively and quantitatively analyzed. The results showed that delayed harvest decreased berry mass and longitudinal diameter. In addition, it increased soluble solid content (SSC) and reduced titrable acid content. A total of 19 anthocyanins, 6 flavanols and 15 flavonols were detected in the berry skin of Merlot. The contents of flavanols and flavonols in grapes harvested 1 week later than normal increased by 69% and 1.67%, respectively, compared with the control, and decreased with delayed harvest time up to 2–3 weeks. The content of anthocyanins decreased with delayed harvest. A total of 15 anthocyanins, 4 flavanols and 15 flavonols were detected in the berry skin of Cabernet Sauvignon. When harvest was delayed by 3 weeks, the contents of anthocyanins, flavanols and flavonols increased by 22%, 102%, and 80% compared with the control, respectively.
